Combinations of filters can be optional laravel eloquent relationships

I want to filter replies based on query parameter passed, query parameters can be post_id, comment_id and array of reply_ids all can be optional and can be used as combination

 $query = Post::where('user_id', auth()->id());
    if ( isset($data['reply_ids']) ) {
        $query = $query->with('posts.comments.replies')->whereHas('posts.comments.replies', function($query) use ($data){
            $query->whereIn('id', $data['reply_ids']);
        });
    }

Now, if I want to filter again with comment authors, that is on comments table, if I want to add filters of post author, that will be on posts table, how I can add those conditional, and still that will be optional?
